Renowned for making some of the best sports watches, Coros has moved into the heart rate monitor market with the launch of the Coros Heart Rate Monitor. This excellent device is one of the best heart rate monitors around, mainly due to how easy it is to use: Just slip it on your arm and it turns itself on, links with your watch and starts tracking.
I found the monitor accurate when compared with a chest strap heart rate monitor in my testing, and the battery life is good enough for weeks of workouts. It’s light on features relative to the Polar Verity Sense, and chest straps are available for less, but the Coros HRM is appealingly simple to use if you prefer to wear an armband.
